[ILUG] Checking for a modem?

[Martin Donlon]

well, in C you could open a pipe(2) to the serial device.
send a "ATZ\n" and if theres a modem there you should get a "OK" back
If you don't want to reset the modem you could try just sending a "AT\n"
which should return a "OK" unless numeric responses are on (ATV0).

Not too sure how to go about doing this from the shell.
